I would vouch for this entirely:
"But cars are meant to be driven, not sitting, so unless you go through extreme measures for long-term storage, you are doing more harm than good by letting it just sit there."
Everytime I leave the daily driven car at home for 2 weeks when we're away, there always seem to be a problem somewhere when I return. Well stored or not, something just had to be changed. The more I drive of the 300SE, the lesser the replacements would be. There certainly is a correlation.
